Application filed September 10, 1909. Serial No. 517,053.

To all 'whom t may concern.'

Be it known that we, JOHN F. SHERLOCK and HENRY SPENGLER, residing atNew York,

, vices, and particularly to amusement devices which can be utilized inan educational way, as for the teaching of geography.

One of the objects of the invention is to provide a hollow body, as aglobe, within which is freely movable a magnet, so disposed that itmaintains a constant relation to the wall 'of the body, and a keeper forsaid magnet formed into or having secured thereto the simulation of someobject, as for instance a ship, sliding upon the outside of the globe asthe magnet is caused to move relatively thereto. A

Another object of the invention is to provide a new and part-icularlyadvantageous form of support for the magnet, whereby the action of thedevice is rendered especially sensitive, the cost of manufactureminimized, and diliiculty of assembling and of maintaining in operativeassembled rela- -tion obviated.

A further object, where the device is intended to show the movements ofa ship traveling from point to point upon the water-covered part o-ftheearths surface, is to furnish the simulant globe with land portionsin relief; or by some other means to prevent the traveling keeper-frommoving over portions of the globe surface incongruous with the supposedcharacter of the former.

Other objects and aims of the invention, together with inherentadvantages thereof, will be in part obvious and in part specificallyadvert'ed to in the course of the following description, wherein theelements, combinations and arrangements of parts constituting theinvention will be fully set forth, after which the scopel of theapplication thereof will be defined in the appended claims.

In the accompanying drawings, which are 'to be taken as apart of thisspecification,

and in which we have illustrated a merely preferred form of embodimentof the invention; Figure lis a View of a geographical globe embodyingthe invention, looking down upon the same; and Fig. 2 is a centralsection through the same.` y

Referring to the numerals on the drawings, 1 and 2 indicate hemisphereswhich may be united by an overlapping joint 3 to form a globe. Theoutside of said globe is preferably covered `with a representation ofthe earths surface, exhibiting the oceans, continents, &c.

4 indicates a supporting member which is hemisphcrical if the hollowbody is a globe, as just described. For the sake of stability the member'4 may be of but little smaller diameter than the globe, and when it isin position, as shown in Fig. 2, it is concentric with the globe. Aseries, preferably four, of

pockets 5 is formed in the member 4, to rcceive anti-friction rollers 6,or the like, through which member 4 bears on thc 1uner wall of theglobe.' The function .of

to keep the supporting member 4 always at the bot-tom of the globe; andwith its poles extending very nearly to the opposite inner wall of theglobe, the ends of the poles being shaped conformably to said wall. Thebest disposition of the magnet appearsto be the one shown, that is,centrally of its support and ,therefore diametrically of the globe.

lt will be evident that if the globe be turned in any direction themember 4, because of its ownweight and that of the ballast it carries,will tend to remain at'the bottom of the globe, the balls 6 sliding orrolling over the inner wall thereof. Consequently the active end of themagnet will move in acorresponding path always opposite of member 4. I

It is evident that, the globe, member 4, ballast, &c.`; all being ofnon-magnetic material, if asuitable magnetizable object l0 be placedoutside the globe opposite the poles of the magnet, it will be held bythe atits surface, held in its approximate relation to the magnet.Accordingly, by proper manipulationof the globe the magnet-ized objectmay be given the appearance of movement over the globe. In the drawingssaid magnetized object simulates a ship, and movement of the globecauses it apparently to slide over the surface of the earth.

In order that it may be impossible for ship to travel over any exceptthe watersimulating surface of the globe, we throw the land part thereofinto high relief, as shown, so that it will constitute a stop to thetravel of the ship. Even though the ship should be attracted onto theland surface, the distance from the magnet is thus increased to such anextent that the attractive force of the latteris of no effect, and

the ship will fall off. If'the object 10 represented-some land travelingobject, of course, a different arrangement would have to be made.

Obviously the device described, while of use as a toy, is also a veryexcellent illustration of certain principles of physics, as well as anaid in the teaching of geography.

It may be noted that the form of magnet employed may be changed, as alsothat of the supporting member, thoughl means should be provided formaintaining the ef- 'fective end of the latter in some constantposition, preferably at the top of the globe.

'As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be taken as illustrative, and not in a limiting sense.

It is also `to be understood that materials, sizes, and relativities ofparts are unimportant, except as they are called .for in the followingclaims, which define the Vscope'of invention contemplated.

Having thus described our invention, what we claim as newl and v.desireto secure'gby Letters Patent., is:

1. In a device of the kind described, a hollow globe having geographicalmarkings on its outer surface, a hollow hemispherical magnet supportwithin said body, regularly spaced depressions being formed in the outersurface of said support, antifriction balls within said depressionsadapted to bear against the inner wall of the hollow globe,

ballast carried within the hemispherical support at a point farthestfrom the edge against the inner wall ofthe hollow globe,

ballast carried within the hemispherical support at a. point farthestfrom t e edge thereof, a magnet on said support held in place by saidballast and a keeper for the magnet on the outside of the globe,portions of the outer surface of the globe being in high relief.

y 3. In combination with a hollow shell or globe, a magnet carried by'arelatively heavy base having smooth and rounded bearings or supports onits under face, substantially as described.

In testimony whereof we aiiix our signatures in the presence of twowitnesses.
